space with a horizontal range of -1920 to 1920, and a vertical range of -1080 to 1080. This
allows positioning of the image so that a portion of it is displayed within the constraints of
the output raster (output resolution), or off the screen entirely.
NOTES:
• The available range of the image position depends on the horizontal and vertical
USB output resolution. The image can be shifted off screen only by the amount of
the horizontal and vertical streaming resolution.
• Size and position values must be divisible by 8 (horizontal) or 2 (vertical).
Figure 68 below shows the line and pixel coordinates at which the image can be positioned.
